Carotid energy pulsatility index provides complementary hemodynamic information to renal function in a community-based cohort

Abstract Conventional hemodynamic, including Carotid–femoral pulse wave velocity (cfPWV), characteristic impedance (Zc), and brachial pulse pressure, do not directly quantify pulsatile energy transmission through the arterial system. Carotid energy pulsatility index (PI), derived...

CodaRAG: Connecting the Dots with Associativity Inspired by Complementary Learning

Large Language Models (LLMs) struggle with knowledge-intensive tasks due to hallucinations and fragmented reasoning over dispersed information. While Retrieval-Augmented Generation (RAG) grounds generation in external sources, existing methods often treat evidence as isolated uni...

Hyperglycemia induces endothelial mitochondrial dysfunction and myeloperoxidase dysregulation in PCOS iPSCs

Polycystic ovary syndrome (PCOS) is associated with increased risks of cardiovascular disease (CVD), driven in part by endothelial dysfunction. Using patient-derived induced pluripotent stem cells (iPSCs), we established an endothelial model to examine cellular responses to metab...

Pseudobulb Yield and Chemical Quality of Field-Grown Bletilla formosana in Guangfu, Hualien, Across Cultivation Years and Harvest Seasons

Bletilla formosana is an important medicinal orchid in Taiwan, but information on how cultivation year, harvest season, and pseudobulb size are associated with yield and chemical quality under field conditions remains limited. This study evaluated field-grown B. formosana in Guan...

Redefining Kidney Stone Incidence: Emerging Age-Related Patterns

OBJECTIVE: To evaluate the association between age and incident kidney stone disease using contemporary, age- and sex-stratified population-based data from the UK Biobank. METHODS: We undertook a cohort study of 494,745 UK Biobank participants after excluding 7406 individuals wit...

Coordination‐Asymmetry‐Regulated Reconstruction of Electron‐Rich Cu Sites for pH‐Dependent Nitrate‐to‐Ammonia Electrocatalysis

ABSTRACT Electrocatalytic nitrate reduction reaction ( e‐ NO 3 RR) offers a promising route to valorize nitrate‐contaminated wastewater while enabling sustainable ammonia production; however, how local coordination asymmetry regulates Cu‐site evolution and reaction pathways acros...

Crowding‐driven condensation and membrane reorganization

Abstract Although biological membranes exhibit complex and dynamic organization, the mechanistic role of molecular crowding in governing lateral membrane heterogeneity remains poorly characterized experimentally. Here, we provide direct experimental visualization showing that cro...

Targeting the Gut to Modify Parkinson's Disease: From Mechanisms to Potential Therapeutics

Parkinson's disease (PD) is the second most common neurodegenerative disorder and its prevalence continues to rise with population aging. Its cardinal motor features arise from the loss of dopaminergic neurons in the substantia nigra, accompanied by intraneuronal α-synuclein aggr...

Gauss law constraint in A-theory branes

{\cal A} -theory realizes U-duality symmetry by extending the string worldsheet to a higher dimensional brane worldvolume, in which the worldvolume and the spacetime belong to different representations of the exceptional group. The closure of the brane Virasoro algebra requires t...

Dimensional Engineering of Co/W Superlattices Enables Out-of-Plane Spin Polarization with 90% Field-Free Switching in Perpendicular CoFeB

Abstract Deterministic spin–orbit torque (SOT) switching of perpendicular magnets without external magnetic fields remains a central challenge for scalable SOT-MRAM. Here, we demonstrate that dimensional engineering of a Co/W superlattice spin–orbit layer enables >90% field-free...

Ensemble Voting of Large Language Models for Multiple-Choice Answer Prediction

Machine Reading Comprehension (MRC) has become a key benchmark for evaluating natural language processing systems, and multiple-choice question answering is widely adopted for assessing reasoning, comprehension, and commonsense inference capabilities. However, traditional embeddi...

Lacunary δ‐Discretized Spherical Maximal Operators

ABSTRACT We study the lacunary analog of the ‐discretized spherical maximal operators introduced by Hickman and Jančar, for , and establish the boundedness on for all , along with the endpoint weak‐type estimate . We also prove the corresponding boundedness for the multi‐paramete...

Clinical Implications of the Novel Genetic Polymorphism Associated With Retinal Vein Occlusion: The East Asian GWAS Survey in a Single-Center Taiwanese Cohort

Purpose: To explore the single-nucleotide polymorphic features in an East Asian cohort of retinal venous occlusion (RVO) patients, to map pathogenic genes, and to analyze potential pathophysiological associations. Methods: This was a cross-sectional monocentric cohort study invol...

The Evolving Role of Pharmacists in Doping Prevention: A Scoping Review

CONTEXT: Doping and inadvertent exposure to prohibited substances are major concerns in sport because of their implications for athlete health, medication safety, and fair competition. The growing use of prescription medications, over-the-counter products, and dietary supplements...

Integrating generative artificial intelligence facilitates faculty interaction network and role transition in a biostatistics curriculum

In a two-year action-research study within an undergraduate biostatistics curriculum for nursing, pharmacy, and medical biotechnology students, we examined how generative artificial intelligence (GenAI) facilitates educators to design, supervise, and evaluate learning. Students u...

Diagnosis of tuberculous lymphadenopathy: the role of droplet digital PCR

Background: Tuberculous lymphadenopathy (TB-LAP) is the most common form of extrapulmonary TB and remains diagnostically challenging due to its paucibacillary nature. We evaluated the diagnostic performance of droplet digital PCR (ddPCR) for detecting Mycobacterium tuberculosis (...

ABSTRACT Achieving a homogeneous ion‐conducting network with sufficient mechanical strength and interfacial stability in Succinonitrile (SN)‐polyethylene oxide (PEO)‐based solid polymer electrolytes remains challenging. In particular, the temperature‐dependent interfacial behavio...

Enabling Efficient NIR‐III Emission Under 808 nm Excitation Through Tm 3+ to Ho 3+ Energy Transfer

ABSTRACT Near‐infrared‐III (NIR‐III, 1700–2500 nm) phosphors are promising for deep‐tissue imaging and long‐wavelength photonic applications but are limited by weak excitation compatibility, low efficiency, and severe thermal quenching. Here, we report a Y 2 GeO 5 :Tm 3+ ,Ho 3+ p...

What Persists Matters More Than What Changes

A reusable world model need not reproduce every future observation exactly. What matters is which distinctions remain stable when forecasts, tasks, or trained instances change. Independently trained models may give different values yet preserve the same relation among matched int...
